Waves of high school students across the country marched out of class on Wednesday to demand stricter gun laws in hopes of putting an end to school massacres once and for all.

This unprecedented National Walkout Day, which kicked off at 10 a.m. EST and will continue across the states at 10 a.m. local time, was sparked by the Parkland, Florida school shooting and fueled by the fire and fury of its articulate survivors.

The protest was initially supposed to be 17 minutes of silence -- one minute for each of the victims gunned down in the Marjory Stoneman Douglas High School Valentine's Day massacre -- but students are opting to stay out of class for much longer to rally for change.

These teens are so undeterred, even the threat of being suspended won't stop them from hitting the pavement to call on Congress to pass stricter, "common sense" gun control laws.
